Abstract: [eng] [cze]
Creating night-time images and movies that look plausible has been a problem in the industry since the creation of camera. To capture an image we need enough light to create a measurable quantity on a camera sensor. For this reason, shooting at night was not possible until sensors sensitive enough were developed and even then the captured images do not look realistic. Movie industry circumvent these issues by manually color correcting the footage in post-production. We implement an algorithm presented in a 2011 SIGGRAPH paper capable of solving this problem in a psycho-physically plausible and consistent way for spectral images and also augment it by a technique taken from a paper by INRIA. 1 Výroba fotiek a filmov zachytávajúca nočnú scenériu, ktorá vyzerá prirodzene, je dlhotrvajúci problém od vzniku fotoaparátu. Pre vytvorenie snímku je potrebné mať dostatok svetla, ktoré v senzore fotoaparátu vytvorí merateľnú veličinu. Kvôly tomu, fotenie v noci nebolo možné kým neboli senzory dosť citlivé, avšak aj potom fotky stále nevyzerali realisticky. Filmový priemysel vyriešil tento problém manuálnou korekciou farieb v postprodukcii. Naim- plementovali sme algoritmus z článku publikovaného v SIGGRAPH 2011, ktorý je schopný na spektrálnych obrazoch tento problém vyriešiť konzis- tentne a vierohodne a rozšírili sme ho o techniku použitú z INRIA článku. 1
